3D model from dicoms

Operating system: Windows 10
Slicer version: 4.10.1
Expected behavior: I need to create an accurate 3D model from my dicom images
Actual behavior: I can’t obtain a good and creal 3D model. I’m quite new to Slicer but, using the free downloadable samples of the software, I never had all these problems at all. I attach some screenshots of my case of study, if it helps.

I’ve been able to import my dicom files as a new patient (i just needed to import them as a non-anonymus file), but I still haven’t found a way to make a proper 3D model of my patient. If I enable the visibility of each volume (one by one) this is the scene I get, the better view I have is this one ("best view " file), but I can’t obtain a clear and good 3d model from it (I’m using the threshold effect). the stl 3d model that I get really sucks. Could you help me with this? What am I doing wrong? Thank you so much for your support!!



First of all, what would you like to segment? Simple thresholding works well in cases when structures of interest have highly distinctive intensity value on the image (bone on CT, contrasted vessels, etc.). If you want to segment bone on MRI then you need to use more sophisticated tools than thresholding.

Another problem is that, quite often 3 anisotropic MRI images are acquired (high resolution along two axes, very low resolution along a third axis) to reduce time spent in the MRI scanner. However, these images are not well suited for 3D model generation. See more information here: Combining volumes - what am I missing?. To reduce artifacts caused by low-resolution third axis you can follow the technique explained here: Segmenting Issue: I Can't Remove "ridges" in 3-D model

Thank you so much for your quick reply. I guessed these images are not suited pro 3d model generation. I read all those information, but I’ll check them again and I’ll keep tryin. thank you again!

You can still build 3D models from these kind of images, but the result will not be very high quality because you cannot utilize the high image resolution within the slice plane if slices are very far from each other.

Yeah I’d love to,but I assume I’m not experienced enough to build good 3d models …i watched tons of tutorials and read all about this but i still haven’t done a beautiful and good model from this files:( this work is really important to me but i can’t understand how i could make a valid and accurate 3d model

I can do a skype on Sunday and try to advice


Hi Ron, thank you so much for your support. Unfortunately I think I won’t be able to do a skype this week, but I’d be glad to keep in touch and talk more about it with you via email, if possibile. I’d need this 3D model for surgical planning use, so I’d love to discuss about it with you, if you wish. My email address is giuls.berg@gmail.com
Thank you again,
